摘要 目的分析早产新生儿监护病房(PNICU)内早产儿真菌性败血症的临床特点,为其诊治及预防提供参考依据。方法对PNICU 21例确诊为真菌性败血症早产儿的临床资料进行回顾性分析。结果 21例真菌性败血症患儿均为<34周早产儿,占同期出院早产儿的1.24%,体质量均<1 800 g,其中极低出生体质量儿10例,超低出生体质量儿2例。21例真菌感染前全部接受广谱抗生素治疗及静脉营养,17例有皮质激素暴露,17例曾机械通气,4例留置中心静脉导管(PICC),4例曾外科胸腔闭式引流,2例曾使用抑酸剂。起病最早为生后10 d,最晚57 d。表现为发热、呼吸暂停、灌注差、惊厥等症状。6例血常规白细胞<5.0×109/L,14例C反应蛋白明显升高,13例血小板<100×109/L,血培养近平滑假丝酵母10例,罗伦特隐球菌3例,无名假丝酵母3例,白色假丝酵母菌2例,季也蒙假丝酵母菌、葡萄牙假丝酵母、粉状毕赤酵母各1例,药敏均提示对二性霉素B敏感,氟康唑敏感率为90.48%。脑脊液检查1例白细胞和蛋白均明显增高,培养与血培养一致。CT检查脑组织大片坏死。21例均接受氟康唑抗真菌及对症支持治疗,15例治愈,5例放弃治疗自动出院,1例死亡。结论 PNICU真菌败血症多见于<34周早产儿,以假丝酵母类最为多见,高危因素包括出生胎龄、体质量、长期应用广谱抗生素、机械通气、皮质激素暴露、外科手术、中心静脉置管等,可伴有白细胞升高或减少、血小板减少、C反应蛋白升高等,氟康唑治疗效果较好。
